基于最小二乘法运动目标标定方法及应用

Calibration Method and Application of Moving Target Based on Least Square Method

为实现对运动目标的有效射击,采用最小二乘法计算运动方向和运动速度。及时且准确地进行目标标定,计算出较为准确的运动诸元,即运动方向和运动速度,从而计算出提前时间阻击点位置坐标和实有阻击点放的时间,实现对运动目标的射击;结合实例有效地验证了最小二乘法计算运动诸元的有效性和正确性,同时提出运动目标射击软件设计的建议。结果表明,该方法具有较强的实用价值和推广意义。

In order to shoot the moving target effectively,the least square method is used to calculate the moving direction and speed.Timely and accurately carrying out target calibration,calculating more accurate motion data,namely motion direction and motion speed,thereby calculating the position coordinates of the blocking point in advance time and the release time of the actual blocking point,and realizing the shooting of the moving target.The validity and correctness of the least square method for calculating the motion data are verified by an example,and the suggestions for the design of the shooting software for moving targets are put forward.The results show that the method has a strong practical value and promotion significance.
